FIELD OF THE INVENTION

The present invention relates to novel 6-6 bicyclic aromatic ring substituted nucleoside analogues useful as PRMT5 inhibitors. The invention further relates to pharmaceutical compositions comprising said compounds as an active ingredient as well as the use of said compounds as a medicament.

BACKGROUND OF THE INVENTION

PRMT5, also described as Hs17, Jbp1, Skb1, Capsuleen or Dart5, is one of the major methyltransferases responsible for mono- and symmetric dimethylation of arginines.

Post-translational arginine methylation on histones and non-histone proteins seems to be crucial for a variety of biological processes, like genome organisation, transcription, differentiation, spliceosome function, signal transduction and regulation of cell-cycle progression, stem cells and T-cell fate [Stopa, N. et al., Cell Mol Life Sci, 2015. 72 (11): p. 2041-59] [Geoghegan, V. et al., Nat Commun, 2015. 6: p. 6758]. Metazoan PRMT5 forms a functional complex with the methylosome protein 50 (MEP50) also named as Wdr77, androgen receptor coactivator p44 and Valois. Both, elevated PRMT5-MEP50 protein level and cytoplasmic accumulation are implicated in cancer tumorigenesis and have recently been correlated with poor clinical outcome [Shilo, K. et al., Diagn Pathol, 2013. 8: p. 201]. Cellular rescue experiments that addressed both the catalytic and scaffold function of the PRMT5-MEP50 complex, beside comprehensive enzymological studies have substantiate the oncogenic link between protein level, localisation and enzymatic function [Gu, Z. et al., Biochem J, 2012. 446 (2): p. 235-41] [Di Lorenzo, A. et. al., FEBS Lett, 2011. 585 (13): p. 2024-31][Chan-Penebre, E. et al., Nat Chem Biol, 2015. 11 (6): p. 432-7]. This correlation turns PRMT5 into an essential small molecule drug target against cancer and other diseases [Stopa, N. et al., Cell Mol Life Sci, 2015. 72 (11): p. 2041-59].

PRMT5 is a member of the type II PRMT subfamily that utilises S-adenosylmethionine (SAM) to generate symmetric dimethylated arginine on histones and non-histone protein substrates and S-adenosylhomocysteine (SAH). The crystal structure of the human hetereo-octameric complex (PRMT5)₄(MEP50)₄ co-crystalised with SAH and a histone H4 peptide substrate illustrated the mechanism of methylation and substrate recognition [Antonysamy, S. et al., Proc Natl Acad Sci USA, 2012. 109 (44): p. 17960-5]. The regulation of PRMT5 activity occurs through a vast number of different binding partners, post-translational modification cross talk, miRNAs and subcellular localisation.

Methylation of histones H2A and H4 on Arg3 and histone H3 on Arg8 regulate chromatin organisation for specific repression of gene transcripts that are involved in differentiation, transformation, cell-cycle progression and tumour suppression [Karkhanis, V. et al., Trends Biochem Sci, 2011. 36 (12): p. 633-41]. Furthermore, PRMT5-mediated methylation of histone H4 on Arg3 might recruit the DNA-methyltransferase DNMT3A to couple histone and DNA methylation for long-term gene silencing [Zhao, Q. et al., Nat Struct Mol Biol, 2009. 16 (3): p. 304-11].

Non-histone methylation can occur either in the cytoplasm or nucleus dependent on the cellular localisation of PRMT5. The methylation of the Sm proteins D1 and D3, which are required for the assembly of the nuclear splicesome, takes place in the cytoplasm as part of the PRMT5 containing “methylosome” [Friesen, W. J. et al., Mol Cell Biol, 2001. 21 (24): p. 8289-300]. Further evidence for PRMT5 involved in splicing has been provided by the conditional PRMT5 knockout in mouse neural stem cells. Cells that lack PRMT5 showed a selective retention of introns and skipping of exons with weak 5′ donor sites [Bezzi, M. et al., Genes Dev, 2013. 27 (17): p. 1903-16].

In addition to a role in splicing, PRMT5 influences key pathways involved in cell fate and homeostasis by direct methylation of key signalling nodules like p53 [Jansson, M. et al., Nat Cell Biol, 2008. 10 (12): p. 1431-9], EGFR [Hsu, J. M. et al., Nat Cell Biol, 2011. 13 (2): p. 174-81], CRAF [Andreu-Perez, P. et al., Sci Signal, 2011. 4 (190): p. ra58], PI3K/AKT [Wei, T. Y. et al., Cell Signal, 2014. 26 (12): p. 2940-50], NFκB [Wei, H. et al., Proc Natl Acad Sci USA, 2013. 110 (33): p. 13516-21].

Since PRMT5 is one of the major sym-Arg methyltransferases and involved in a multitude of cellular processes, an increased protein expression appears to be an important factor in its tumorigenicity. Interestingly, the translation of PRMT5 in mantle cell lymphoma (MCL) seems to be regulated by miRNAs. Although MCL cells show less mRNA and a slower transcription rate of PRMT5 than normal B lymphocytes, the PRMT5 level and the methylation of H3R8 and H4R3 are significantly increased [Pal, S. et al., EMBO J, 2007. 26 (15): p. 3558-69]. Re-expression of miRNAs that binds the 3′UTR region of PRMT5 decreases PRMT5 protein level [Wang, L. et al., Mol Cell Biol, 2008. 28 (20): p. 6262-77]. Strikingly, a prmt5 antisense RNA has been found within the human prmt5 gene that supports the hypothesis of a specific translational regulation rather than high mRNA expression level [Stopa, N. et al., Cell Mol Life Sci, 2015. 72 (11): p. 2041-59].

Although PRMT5 is considered as a clinical relevant target, very few selective PRMT5 inhibitors have been published, yet. Very recently, a novel sub-nanomolar potent PRMT5 inhibitor (EPZ015666) with anti-tumour activity in multiple MCL xenograft models has been described to be the first chemical probe suitable for further validation of PRMT5's biology and role in cancer [Chan-Penebre, E. et al., Nat Chem Biol, 2015. 11 (6): p. 432-7].

Further development of specific small molecule inhibitors of PRMT5 may lead to novel chemotherapeutic approaches for cancer.

In particular, any feature indicated as being preferred or advantageous may be combined with any other feature or features indicated as being preferred or advantageous.

DETAILED DESCRIPTION

When describing the compounds of the invention, the terms used are to be construed in accordance with the following definitions, unless a context dictates otherwise.

When any variable occurs more than one time in any constituent or in any formula (e.g. Formula (I)), its definition in each occurrence is independent of its definition at every other occurrence.

Whenever the term “substituted” is used in the present invention, it is meant, unless otherwise is indicated or is clear from the context, to indicate that one or more hydrogens, in particular from 1 to 3 hydrogens, preferably 1 or 2 hydrogens, more preferably 1 hydrogen, on the atom or radical indicated in the expression using “substituted” are replaced with a selection from the indicated group, provided that the normal valency is not exceeded, and that the substitution results in a chemically stable compound, i.e. a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into a therapeutic agent.

When two or more substituents are present on a moiety they may, unless otherwise is indicated or is clear from the context, replace hydrogens on the same atom or they may replace hydrogen atoms on different atoms in the moiety.

The prefix “C_(x-y)” (where x and y are integers) as used herein refers to the number of carbon atoms in a given group. Thus, a C₁₋₄alkyl group contains from 1 to 4 carbon atoms, a C₁₋₃alkyl group contains from 1 to 3 carbon atoms and so on.

The term “halo” as a group or part of a group is generic for fluoro, chloro, bromo, iodo unless otherwise is indicated or is clear from the context.

The term “C₁₋₄alkyl” as a group or part of a group refers to a hydrocarbyl radical of Formula C_(n)H_(2n+1) wherein n is a number ranging from 1 to 4. C₁₋₄alkyl groups comprise from 1 to 4 carbon atoms, preferably from 1 to 3 carbon atoms, more preferably 1 to 2 carbon atoms. C₁₋₄alkyl groups may be linear or branched and may be substituted as indicated herein. When a subscript is used herein following a carbon atom, the subscript refers to the number of carbon atoms that the named group may contain. C₁₋₄alkyl includes all linear, or branched alkyl groups with between 1 and 4 carbon atoms, and thus includes methyl, ethyl, n-propyl, i-propyl, 2-methyl-ethyl, butyl and its isomers (e.g. n-butyl, isobutyl and tert-butyl), and the like.

The skilled person will realize that the term ‘C₁₋₄alkoxy’ or ‘C₁₋₄alkyloxy’ as a group or part of a group refers to a radical having the Formula —OR^(c) wherein R^(c) is C₁₋₄alkyl. Non-limiting examples of suitable C₁₋₄alkyloxy include methyloxy (also methoxy), ethyloxy (also ethoxy), propyloxy, isopropyloxy, butyloxy, isobutyloxy, sec-butyloxy and tert-butyloxy.

The term “C₂₋₄alkenyl” as used herein as a group or part of a group represents a straight or branched chain hydrocarbon group containing from 2 to 4 carbon atoms and containing a carbon carbon double bond such as, but not limited to, ethenyl, propenyl, butenyl, 1-propen-2-yl, and the like.

The term “C₂₋₆alkenyl” as used herein as a group or part of a group represents a straight or branched chain hydrocarbon group containing from 2 to 6 carbon atoms and containing a carbon carbon double bond such as, but not limited to, ethenyl, propenyl, butenyl, pentenyl, 1-propen-2-yl, hexenyl and the like.

The term ‘C₃₋₆cycloalkyl’ as used herein as a group or part of a group represents cyclic saturated hydrocarbon radicals having from 3 to 6 carbon atoms such as cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl.

In case Z is —X—CR^(5a)R^(5b)—, it is intended that X is attached to Ar.

In case Z is —CR^(5c)═CR^(5d)—, it is intended that the C-atom with the R^(5c) substituent is attached to Ar.

In case Z is —CR^(5e)R^(5g)—CR^(5f)R^(5h)—, it is intended that the C-atom with the R^(5e) and R^(5g) substituents is attached to Ar.

In case Z is —CR^(5a)R^(5b)—X—, it is intended that the C-atom with the R^(5a) and R^(5b) substituents is attached to Ar.

The skilled person will realize that the 4-, 5-, 6- or 7-membered heterocyclic ring being attached to the remainder of the molecule via a ring nitrogen atom (in the definition of R¹²) particularly is a saturated ring. Non-limiting examples of R¹² are 1-piperidinyl, 1-pyrrolidinyl, 1-morpholinyl, 1-azetidinyl, and the like.

It will be clear for the skilled person that, unless otherwise is indicated or is clear from the context, a substituent on a 4- to 7-membered monocyclic aromatic ring containing one, two or three heteroatoms (as in the definition of R¹³) (non-limiting examples are pyrrolyl, pyridinyl, furanyl, and the like), may replace any hydrogen atom on a ring carbon atom or where possible on a ring nitrogen atom (in which case a hydrogen on a nitrogen atom may be replaced by a substituent). It will be clear for the skilled person that the same is applicable to the 6- to 11-membered bicyclic fused aromatic ring containing one, two or three heteroatoms (as in the definition of R¹³) (non-limiting examples are indolyl, quinolinyl, and the like).

A 4- to 7-membered monocyclic aromatic ring containing one, two or three heteroatoms (as in the definition of R¹³), may be attached to the remainder of the molecule of Formula (I) through any available ring carbon or nitrogen atom as appropriate, if not otherwise specified. It will be clear for the skilled person that the same is applicable to the 6- to 11-membered bicyclic fused aromatic ring containing one, two or three heteroatoms (as in the definition of R¹³).

In case a nitrogen atom replaces one of the two fused carbon atoms in the Ar group, a carbonyl group is present in said bicyclic aromatic ring system as exemplified by the structure shown below:

which is optionally substituted according to any of the embodiments. It will be clear this example is non-limiting.

Other, non-limiting, examples of the Ar group being a 10-membered bicyclic aromatic ring system consisting of two fused 6-membered rings, wherein optionally 1 or 2 ring carbon atoms are replaced by a nitrogen atom are shown below:

each of which are optionally substituted according to any of the embodiments.

The skilled person will understand that the 10 members of the 10-membered Ar group (the 10-membered bicyclic aromatic ring system consisting of two fused 6-membered rings, wherein optionally 1 or 2 ring carbon atoms are replaced by a nitrogen atom), are 10 carbon atoms, 9 carbon atoms and 1 nitrogen atom, or 8 carbon atoms and 2 nitrogen atoms. Ar is optionally substituted according to any of the embodiments.

Whenever substituents are represented by chemical structure, “---” represents the bond of attachment to the remainder of the molecule of Formula (I). Lines drawn from substituents into ring systems indicate that the bond may be attached to any of the suitable ring atoms.

For example

covers any one of the following ring systems:

is an alternative representation for

The term “subject” as used herein, refers to an animal, preferably a mammal (e.g. cat, dog, primate or human), more preferably a human, who is or has been the object of treatment, observation or experiment.

The term “therapeutically effective amount” as used herein, means that amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue system, animal or human that is being sought by a researcher, veterinarian, medicinal doctor or other clinician, which includes alleviation or reversal of the symptoms of the disease or disorder being treated.

The term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combinations of the specified ingredients in the specified amounts.

The term “treatment”, as used herein, is intended to refer to all processes wherein there may be a slowing, interrupting, arresting or stopping of the progression of a disease, but does not necessarily indicate a total elimination of all symptoms.

The term “compounds of the (present) invention” as used herein, is meant to include the compounds of Formula (I) and pharmaceutically acceptable addition salts, and solvates thereof.

Some of the compounds of Formula (I) may also exist in their tautomeric form. The term “tautomer” or “tautomeric form” refers to structural isomers of different energies which are interconvertible via a low energy barrier. For example, proton tautomers (also known as prototropic tautomers) include interconversions via migration of a proton, such as keto-enol and imine-enamine isomerisations. Valence tautomers include interconversions by reorganisation of some of the bonding electrons.

Such forms in so far as they may exist, although not explicitly indicated in the above Formula (I), are intended to be included within the scope of the present invention.

As used herein, any chemical formula with bonds shown only as solid lines and not as solid wedged or hashed wedged bonds, or otherwise indicated as having a particular configuration (e.g. R, S) around one or more atoms, contemplates each possible stereoisomer, or mixture of two or more stereoisomers. Where the stereochemistry of any particular chiral atom is not specified in the structures shown herein, then all stereoisomers are contemplated and included as the compounds of the invention, either as a pure stereoisomer or as a mixture of two or more stereoisomers.

Hereinbefore and hereinafter, the term “compound of Formula (I)” is meant to include the stereoisomers thereof and the tautomeric forms thereof. However where stereochemistry, as mentioned in the previous paragraph, is specified by bonds which are shown as solid wedged or hashed wedged bonds, or are otherwise indicated as having a particular configuration (e.g. R, S), then that stereoisomer is so specified and defined. It will be clear this also applies to subgroups of Formula (I).

It follows that a single compound may, where possible, exist in both stereoisomeric and tautomeric form.

The terms “stereoisomers”, “stereoisomeric forms” or “stereochemically isomeric forms” hereinbefore or hereinafter are used interchangeably.

Enantiomers are stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a racemate or racemic mixture.

Atropisomers (or atropoisomers) are stereoisomers which have a particular spatial configuration, resulting from a restricted rotation about a single bond, due to large steric hindrance. All atropisomeric forms of the compounds of Formula (I) are intended to be included within the scope of the present invention.

Diastereomers (or diastereoisomers) are stereoisomers that are not enantiomers, i.e. they are not related as mirror images. If a compound contains a double bond, the substituents may be in the E or the Z configuration. Substituents on bivalent cyclic (partially) saturated radicals may have either the cis- or trans-configuration; for example if a compound contains a disubstituted cycloalkyl group, the substituents may be in the cis or trans configuration. Therefore, the invention includes enantiomers, atropisomers, diastereomers, racemates, E isomers, Z isomers, cis isomers, trans isomers and mixtures thereof, whenever chemically possible.

The meaning of all those terms, i.e. enantiomers, atropisomers, diastereomers, racemates, E isomers, Z isomers, cis isomers, trans isomers and mixtures thereof are known to the skilled person.

The absolute configuration is specified according to the Cahn-Ingold-Prelog system. The configuration at an asymmetric atom is specified by either R or S. Resolved stereoisomers whose absolute configuration is not known can be designated by (+) or (−) depending on the direction in which they rotate plane polarized light. For instance, resolved enantiomers whose absolute configuration is not known can be designated by (+) or (−) depending on the direction in which they rotate plane polarized light.

When a specific stereoisomer is identified, this means that said stereoisomer is substantially free, i.e. associated with less than 50%, preferably less than 20%, more preferably less than 10%, even more preferably less than 5%, in particular less than 2% and most preferably less than 1%, of the other stereoisomers. Thus, when a compound of Formula (I) is for instance specified as (R), this means that the compound is substantially free of the (S) isomer; when a compound of Formula (I) is for instance specified as E, this means that the compound is substantially free of the Z isomer; when a compound of Formula (I) is for instance specified as cis, this means that the compound is substantially free of the trans isomer.

For therapeutic use, salts of the compounds of Formula (I) and solvates thereof, are those wherein the counterion is pharmaceutically acceptable. However, salts of acids and bases which are non-pharmaceutically acceptable may also find use, for example, in the preparation or purification of a pharmaceutically acceptable compound. All salts, whether pharmaceutically acceptable or not are included within the ambit of the present invention.

Pharmaceutically-acceptable salts include acid addition salts and base addition salts. Such salts may be formed by conventional means, for example by reaction of a free acid or a free base form with one or more equivalents of an appropriate acid or base, optionally in a solvent, or in a medium in which the salt is insoluble, followed by removal of said solvent, or said medium, using standard techniques (e.g. in vacuo, by freeze-drying or by filtration). Salts may also be prepared by exchanging a counter-ion of a compound of the invention in the form of a salt with another counter-ion, for example using a suitable ion exchange resin.

The pharmaceutically acceptable addition salts as mentioned hereinabove or hereinafter are meant to comprise the therapeutically active non-toxic acid and base addition salt forms which the compounds of Formula (I) and solvates thereof, are able to form.

Appropriate acids comprise, for example, inorganic acids such as hydrohalic acids, e.g. hydrochloric or hydrobromic acid, sulfuric, nitric, phosphoric and the like acids; or organic acids such as, for example, acetic, propanoic, hydroxyacetic, lactic, pyruvic, oxalic (i.e. ethanedioic), malonic, succinic (i.e. butanedioic acid), maleic, fumaric, malic, tartaric, citric, methanesulfonic, ethanesulfonic, benzenesulfonic, p-toluenesulfonic, cyclamic, salicylic, p-aminosalicylic, pamoic and the like acids. Conversely said salt forms can be converted by treatment with an appropriate base into the free base form.

The compounds of Formula (I) and solvates thereof containing an acidic proton may also be converted into their non-toxic metal or amine addition salt forms by treatment with appropriate organic and inorganic bases.

Appropriate base salt forms comprise, for example, the ammonium salts, the alkali and earth alkaline metal salts, e.g. the lithium, sodium, potassium, magnesium, calcium salts and the like, salts with organic bases, e.g. primary, secondary and tertiary aliphatic and aromatic amines such as methylamine, ethylamine, propylamine, isopropylamine, the four butylamine isomers, dimethylamine, diethylamine, diethanolamine, dipropylamine, diisopropylamine, di-n-butylamine, pyrrolidine, piperidine, morpholine, trimethylamine, triethylamine, tripropylamine, quinuclidine, pyridine, quinoline and isoquinoline; the benzathine, N-methyl-D-glucamine, hydrabamine salts, and salts with amino acids such as, for example, arginine, lysine and the like. Conversely the salt form can be converted by treatment with acid into the free acid form.

For the purposes of this invention prodrugs are also included within the scope of the invention.

The term “prodrug” of a relevant compound of the invention includes any compound that, following oral or parenteral administration, in particular oral administration, is metabolised in vivo to a form that compound in an experimentally-detectable amount, and within a predetermined time (e.g. within a dosing interval of between 6 and 24 hours (i.e. once to four times daily)). For the avoidance of doubt, the term “parenteral” administration includes all forms of administration other than oral administration, in particular intravenous (IV), intramuscular (IM), and subcutaneous (SC) injection. Prodrugs may be prepared by modifying functional groups present on the compound in such a way that the modifications are cleaved, in vivo when such prodrug is administered to a mammalian subject. The modifications typically are achieved by synthesising the parent compound with a prodrug substituent. In general, prodrugs include compounds of the invention wherein a hydroxyl, amino, sulfhydryl, carboxy or carbonyl group in a compound of the invention is bonded to any group that may be cleaved in vivo to regenerate the free hydroxyl, amino, sulfhydryl, carboxy or carbonyl group, respectively; in particular wherein a hydroxyl group in a compound of the invention is bonded to any group (e.g. —C(═O)—C₁₋₄alkyl) that may be cleaved in vivo to regenerate the free hydroxyl. Within the context of this invention, prodrugs in particular are compounds of Formula (I) or subgroups thereof wherein R¹ and/or R² represent —C(═O)—C₁₋₄alkyl.

Examples of prodrugs include, but are not limited to, esters and carbamates of hydroxy functional groups, esters groups of carboxyl functional groups, N-acyl derivatives and N-Mannich bases. General information on prodrugs may be found e.g. in Bundegaard, H. “Design of Prodrugs” p. 1-92, Elesevier, New York-Oxford (1985).

The term solvate comprises the hydrates and solvent addition forms which the compounds of Formula (I) are able to form, as well as pharmaceutically acceptable addition salts thereof. Examples of such forms are e.g. hydrates, alcoholates and the like.

The compounds of the invention as prepared in the processes described below may be synthesized in the form of mixtures of enantiomers, in particular racemic mixtures of enantiomers, that can be separated from one another following art-known resolution procedures. A manner of separating the enantiomeric forms of the compounds of Formula (I), and pharmaceutically acceptable addition salts, and solvates thereof, involves liquid chromatography using a chiral stationary phase. Said pure stereochemically isomeric forms may also be derived from the corresponding pure stereochemically isomeric forms of the appropriate starting materials, provided that the reaction occurs stereospecifically. Preferably if a specific stereoisomer is desired, said compound would be synthesized by stereospecific methods of preparation. These methods will advantageously employ enantiomerically pure starting materials.

The present invention also embraces isotopically-labeled compounds of the present invention which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature (or the most abundant one found in nature).

All isotopes and isotopic mixtures of any particular atom or element as specified herein are contemplated within the scope of the compounds of the invention, either naturally occurring or synthetically produced, either with natural abundance or in an isotopically enriched form. Exemplary isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine and iodine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹³O, ¹⁵O, ¹⁷O, ¹⁸O, ³²P, ³³P, ³⁵S, ¹⁸F, ³⁶Cl, ¹²²I, ¹²³I, ¹²⁵I, ¹³¹I, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br and ⁸²Br. Preferably, the radioactive isotope is selected from the group of ²H, ³H, ¹¹C and ¹⁸F. More preferably, the radioactive isotope is ²H. In particular, deuterated compounds are intended to be included within the scope of the present invention.

Certain isotopically-labeled compounds of the present invention (e.g., those labeled with ³H and ¹⁴C) are useful in compound and for substrate tissue distribution assays. Tritiated (³H) and carbon-14 (¹⁴C) isotopes are useful for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Positron emitting isotopes such as ¹⁵O, ¹³N, ¹¹C and ¹⁸F are useful for positron emission tomography (PET) studies to examine substrate receptor occupancy.

The compounds of the present invention may also have therapeutic applications in sensitising tumour cells for radiotherapy and chemotherapy.

Hence the compounds of the present invention may be used as “radiosensitizer” and/or “chemosensitizer” or can be given in combination with another “radiosensitizer” and/or “chemosensitizer”.

The term “radiosensitizer”, as used herein, is defined as a molecule, preferably a low molecular weight molecule, administered to animals in therapeutically effective amounts to increase the sensitivity of the cells to ionizing radiation and/or to promote the treatment of diseases which are treatable with ionizing radiation.

The term “chemosensitizer”, as used herein, is defined as a molecule, preferably a low molecular weight molecule, administered to animals in therapeutically effective amounts to increase the sensitivity of cells to chemotherapy and/or promote the treatment of diseases which are treatable with chemotherapeutics.

Several mechanisms for the mode of action of radiosensitizers have been suggested in the literature including: hypoxic cell radiosensitizers (e.g., 2-nitroimidazole compounds, and benzotriazine dioxide compounds) mimicking oxygen or alternatively behave like bioreductive agents under hypoxia; non-hypoxic cell radiosensitizers (e.g., halogenated pyrimidines) can be analogues of DNA bases and preferentially incorporate into the DNA of cancer cells and thereby promote the radiation-induced breaking of DNA molecules and/or prevent the normal DNA repair mechanisms: and various other potential mechanisms of action have been hypothesized for radiosensitizers in the treatment of disease.

Many cancer treatment protocols currently employ radiosensitizers in conjunction with radiation of x-rays. Examples of x-ray activated radiosensitizers include, but are not limited to, the following: metronidazole, misonidazole, desmethylmisonidazole, pimonidazole, etanidazole, nimorazole, mitomycin C, RSU 1069, SR 4233, E09, RB 6145, nicotinamide, 5-bromodeoxyuridine (BUdR), 5-iododeoxyuridine (UdR), bromodeoxycytidine, fluorodeoxyuridine (FudR), hydroxyurea, cisplatin, and therapeutically effective analogs and derivatives of the same.

Photodynamic therapy (PDT) of cancers employs visible light as the radiation activator of the sensitizing agent. Examples of photodynamic radiosensitizers include the following, but are not limited to: hematoporphyrin derivatives, Photofrin, benzoporphyrin derivatives, tin etioporphyrin, pheoborbide-a, bacteriochlorophyll-a, naphthalocyanines, phthalocyanines, zinc phthalocyanine, and therapeutically effective analogs and derivatives of the same.

Radiosensitizers may be administered in conjunction with a therapeutically effective amount of one or more other compounds, including but not limited to: compounds which promote the incorporation of radiosensitizers to the target cells; compounds which control the flow of therapeutics, nutrients, and/or oxygen to the target cells; chemotherapeutic agents which act on the tumour with or without additional radiation; or other therapeutically effective compounds for treating cancer or other diseases.

Chemosensitizers may be administered in conjunction with a therapeutically effective amount of one or more other compounds, including but not limited to: compounds which promote the incorporation of chemosensitizers to the target cells; compounds which control the flow of therapeutics, nutrients, and/or oxygen to the target cells; chemotherapeutic agents which act on the tumour or other therapeutically effective compounds for treating cancer or other disease. Calcium antagonists, for example verapamil, are found useful in combination with antineoplastic agents to establish chemosensitivity in tumor cells resistant to accepted chemotherapeutic agents and to potentiate the efficacy of such compounds in drug-sensitive malignancies.

The compounds of the present invention might also reduce the risk of cancer recurrence.

In view of the utility of the compounds of Formula (I) and pharmaceutically acceptable addition salts, and solvates thereof, there is provided a method of treating warm-blooded animals, including humans, suffering from or a method of preventing warm-blooded animals, including humans, to suffer from any one of the diseases mentioned hereinbefore.

Said methods comprise the administration, i.e. the systemic or topical administration, preferably oral administration, of an effective amount of a compound of Formula (I) or a pharmaceutically acceptable addition salt, or a solvate thereof, to warm-blooded animals, including humans.

Those of skill in the treatment of such diseases could determine the effective therapeutic daily amount from the test results presented hereinafter. An effective therapeutic daily amount would be from about 0.005 mg/kg to 50 mg/kg, in particular 0.01 mg/kg to 50 mg/kg body weight, more in particular from 0.01 mg/kg to 25 mg/kg body weight, preferably from about 0.01 mg/kg to about 15 mg/kg, more preferably from about 0.01 mg/kg to about 10 mg/kg, even more preferably from about 0.01 mg/kg to about 1 mg/kg, most preferably from about 0.05 mg/kg to about 1 mg/kg body weight. A particular effective therapeutic daily amount might be from about 0.01 to 1.00 g twice a day (BID), more in particular 0.30 to 0.85 g BID; even more in particular 0.40 g BID. The amount of a compound according to the present invention, also referred to here as the active ingredient, which is required to achieve a therapeutically effect will of course, vary on case-by-case basis, for example with the particular compound, the route of administration, the age and condition of the recipient, and the particular disorder or disease being treated.

A method of treatment may also include administering the active ingredient on a regimen of between one and four intakes per day. In these methods of treatment the compounds according to the invention are preferably formulated prior to administration. As described herein below, suitable pharmaceutical formulations are prepared by known procedures using well known and readily available ingredients.

The compounds of the present invention, that can be suitable to treat or prevent cancer or cancer-related conditions, may be administered alone or in combination with one or more additional therapeutic agents. Combination therapy includes administration of a single pharmaceutical dosage formulation which contains a compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof, and one or more additional therapeutic agents, as well as administration of the compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof, and each additional therapeutic agents in its own separate pharmaceutical dosage formulation. For example, a compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof, and a therapeutic agent may be administered to the patient together in a single oral dosage composition such as a tablet or capsule, or each agent may be administered in separate oral dosage formulations.

While it is possible for the active ingredient to be administered alone, it is preferable to present it as a pharmaceutical composition.

Accordingly, the present invention further provides a pharmaceutical composition and, as active ingredient, a therapeutically effective amount of a compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof.

Accordingly, the present invention further provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and, as active ingredient, a therapeutically effective amount of a compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof.

The carrier or diluent must be “acceptable” in the sense of being compatible with the other ingredients of the composition and not deleterious to the recipients thereof.

For ease of administration, the subject compounds may be formulated into various pharmaceutical forms for administration purposes. The compounds according to the invention, in particular the compounds of Formula (I) and pharmaceutically acceptable addition salts, and solvates thereof, or any subgroup or combination thereof may be formulated into various pharmaceutical forms for administration purposes. As appropriate compositions there may be cited all compositions usually employed for systemically administering drugs.

To prepare the pharmaceutical compositions of this invention, an effective amount of the particular compound as the active ingredient is combined in intimate admixture with a pharmaceutically acceptable carrier, which carrier may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirable in unitary dosage form suitable, in particular, for administration orally, rectally, percutaneously, by parenteral injection or by inhalation. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs, emulsions and solutions; or solid carriers such as starches, sugars, kaolin, diluents, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit forms in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, to aid solubility, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable solutions containing a compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof, may be formulated in an oil for prolonged action. Appropriate oils for this purpose are, for example, peanut oil, sesame oil, cottonseed oil, corn oil, soybean oil, synthetic glycerol esters of long chain fatty acids and mixtures of these and other oils. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wetting agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not introduce a significant deleterious effect on the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on, as an ointment. Acid or base addition salts of compounds of Formula (I) due to their increased water solubility over the corresponding base or acid form, are more suitable in the preparation of aqueous compositions.

It is especially advantageous to formulate the aforementioned pharmaceutical compositions in unit dosage form for ease of administration and uniformity of dosage. Unit dosage form as used herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such unit dosage forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, suppositories, injectable solutions or suspensions and the like, and segregated multiples thereof.

In order to enhance the solubility and/or the stability of the compounds of Formula (I) and pharmaceutically acceptable addition salts, and solvates thereof, in pharmaceutical compositions, it can be advantageous to employ α-, β- or γ-cyclodextrins or their derivatives, in particular hydroxyalkyl substituted cyclodextrins, e.g. 2-hydroxypropyl-β-cyclodextrin or sulfobutyl-β-cyclodextrin. Also co-solvents such as alcohols may improve the solubility and/or the stability of the compounds according to the invention in pharmaceutical compositions.

Depending on the mode of administration, the pharmaceutical composition will preferably comprise from 0.05 to 99% by weight, more preferably from 0.1 to 70% by weight, even more preferably from 0.1 to 50% by weight of the compound of Formula (I), a pharmaceutically acceptable addition salt, or a solvate thereof, and from 1 to 99.95% by weight, more preferably from 30 to 99.9% by weight, even more preferably from 50 to 99.9% by weight of a pharmaceutically acceptable carrier, all percentages being based on the total weight of the composition.

As another aspect of the present invention, a combination of a compound of the present invention with another anticancer agent is envisaged, especially for use as a medicine, more specifically for use in the treatment of cancer or related diseases.

For the treatment of the above conditions, the compounds of the invention may be advantageously employed in combination with antibody based immune cell redirection, for example T-cell/neutrophil redirection. This can be achieved for example by the use of bispecific monoclonal antibodies or artificial T-cell receptors.

For the treatment of the above conditions, the compounds of the invention may be advantageously employed in combination with one or more other medicinal agents, more particularly, with other anti-cancer agents or adjuvants in cancer therapy.

Example A6

Preparation of Intermediate 14

Step a)

An oven-dried flask was charged with 7-bromo-4-(methylthio)pyrrolo[2,1-f][1,2,4]triazine (45.0 g, 184 mmol) and dry THF (1.20 L) under N₂. The yellow solution was cooled to −78° C., and a yellow suspension was formed. n-BuLi (2.5 M, 79.6 mL) was added dropwise to the reaction mixture over period of 25 minutes at −78° C. The reaction mixture was stirred at −78° C. for 1 hour and a yellow-brown solution formed. A pre-cooled solution of intermediate 10 (84.0 g, 201 mmol) in dry THF (800 mL) in another flask (−78° C.) was added to the solution under N₂. The resulting red-brown solution was stirred at −78° C. for 1.5 h. 2 batches were carried out in parallel. The reaction was quenched by addition of a saturated NH₄Cl aqueous solution (300 mL) at −78° C., and subsequently the mixture was warmed to 10° C. The mixture was extracted with ethyl acetate (500 mL×3). The combined organic layers were washed with brine, dried over MgSO₄, filtered and concentrated under reduced pressure. The residue was load on silica gel then purified by column chromatography (SiO₂, gradient elution: Petroleum ether/Ethyl acetate from 10/1 to 3:1) to afford Intermediate 11 (149 g 56% yield) as an orange gum.

Step b)

To a stirred solution of intermediate 11 (74.0 g, 127 mmol) and triethylsilane (59.9 g, 515 mmol) in DCM (1.80 L) was added BF₃.Et₂O (90.9 g, 640 mmol) dropwise at −30˜−20° C. 2 batches were carried out in parallel. The resulting orange solution was stirred between −30 and −20° C. for 4.5 hours. The reaction mixture was carefully poured into a saturated NaHCO₃ aqueous solution (2.5 L) with vigorous stirring (gas evolution). The mixture was stirred for 2 hours. The organic layer was separated and the aqueous phase was extracted with DCM (200 mL×3). The combined organic layers were washed with brine (500 mL×2), dried over MgSO₄, filtered and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, gradient elution: petroleum ether:ethyl acetate: from 12:1 to 8:1), affording intermediate 12 as a light yellow gum (125.7 g 83% yield)

Step c)

1M BCl₃ in CH₂Cl₂ (860 mL, 860 mmol) was added dropwise at −78° C. to a stirred solution of intermediate 12 (75.0 g, 132 mmol) in DCM (1.20 L) dropwise over period of 2.5 hour under N₂. The mixture was stirred at −78° C. for 1 hour. The reaction mixture was slowly warmed to −40° C. The reaction mixture was poured into MeOH (2.5 L, 20° C.) with stirring. The resulting red solution was stirred for 3 hours. Water (250 mL) was added into the mixture and left at 20° C. for 16 h. The solution was portion wise poured onto solid NaHCO₃ (500 g) carefully with vigorous stirring (gas evolution, the color of mixture was turned from orange-red to yellow). The resulting suspension was filtered and the filtrate was concentrated under reduced pressure. The residue was dispensed in iPrOH/CH₂Cl₂ (1:3, 1 L) then filtered (to remove some inorganic salt) and the filtrate was concentrated under reduced pressure. The residue was triturated with petroleum ether (500 mL×3) to afford crude intermediate 13 (40.2 g, crude) as an orange solid, which used in the next reaction step without further purification.

Step d)

To a suspension of intermediate 13 (40.2 g, crude) and 2,2-dimethoxypropane (34 mL, 277 mmol) in acetone (600 mL) was added TsOH.H₂O (5.92 g, 31.10 mmol, 0.23 eq) at 25° C. (pH=2). The resulting mixture was heated at 60° C. for 2 hours. After being cooled to 25° C., the reaction mixture was concentrated under reduced pressure. The residue was partitioned between ethyl acetate (500 mL) and saturated aqueous NaHCO₃ solution (500 mL). The layers were separated and the aqueous phase was extracted with ethyl acetate (200 mL×3). The combined organic layers were washed with brine (100 mL), dried over MgSO₄, filtered and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, gradient elution: CH₂Cl₂/Ethyl acetate from 10/1 to 6/1). The fractions containing desired intermediate 14 were combined and concentrated under reduced pressure. The residue (28 g, about 80% purity) was purified again by column chromatography (silica gel, gradient elution: Petroleum ether/Ethyl acetate: from 20/1 to 4/1). The desired fractions were combined and concentrated under reduced pressure. The residue was diluted with CH₂Cl₂ (15 mL) then petroleum ether/ethyl acetate (4:1, 200 mL) was added. The mixture was concentrated to about 150 mL and solids were precipitated. The slurry was diluted with petroleum ether to about 400 mL and stirred for 16 hours at 20° C. The mixture was filtered and the solid was rinsed with petroleum ether/ethyl acetate (20/1, 100 mL). The solids were collected and dried under high vacuum to afford pure intermediate 14 as white solid (18.6 g 42% yield for 2 steps).

LCMS (Liquid Chromatography/Mass Spectrometry)

The High Performance Liquid Chromatography (HPLC) measurement was performed using a LC pump, a diode-array (DAD) or a UV detector and a column as specified in the respective methods. If necessary, additional detectors were included (see table of methods below).

Flow from the column was brought to the Mass Spectrometer (MS) which was configured with an atmospheric pressure ion source. It is within the knowledge of the skilled person to set the tune parameters (e.g. scanning range, dwell time . . . ) in order to obtain ions allowing the identification of the compound's nominal monoisotopic molecular weight (MW). Data acquisition was performed with appropriate software.

Compounds are described by their experimental retention times (R_(t)) and ions. If not specified differently in the table of data, the reported molecular ion corresponds to the [M+H]⁺ (protonated molecule) and/or [M−H]⁻ (deprotonated molecule). In case the compound was not directly ionizable the type of adduct is specified (i.e. [M+NH₄]⁺, [M+HCOO]⁻, etc. . . . ). For molecules with multiple isotopic patterns (Br, Cl), the reported value is the one obtained for the lowest isotope mass. All results were obtained with experimental uncertainties that are commonly associated with the method used.

Experimental Procedures In Vitro Assay (Assay 1a and 1b)

Reagents.

PRMT5-MEP50 enzyme was purchased from Charles River (Argenta). The enzyme complex was produced in insect cells (Sf9) infected simultaneously with two baculoviruses. One virus expresses full length human PRMT5 with Flag-tag at N-terminus, the second virus expresses full length MEP50 with His6-TEV cleavage at N-terminus. The protein was affinity purified using anti-Flag (M2) beads eluted with 3×FLAG peptide, followed by His-Select eluted with 0.5M imidazole. Eluted protein was then dialysed against tris-buffered saline (TBS) (pH 8.0) containing 20% glycerol and 3 mM dithiothreitol (DTT).

Full-length untagged human recombinant histone H2A (residues 1-130, Genbank Accession #NM_021052 MW=14.1 kDa) expressed in E. coli was purchased from Reaction Biology Corporation, Cat #HMT-11-146. Reagents used for making reaction buffer or stopping reaction were purchased including Tris base (Sigma Cat #T-1503), NaCl (Sigma Cat #RGF-3270), MgCl₂ (Sigma Cat #M0250), DTTI (Invitrogen Cat #15508-013) and Formic Acid (Riedel deHaen, Cat #33015)

High Throughput Mass Spectrometer Assay

PRMT5 catalyzes the sequential methylations of the terminal nitrogen atoms on the guanidine groups of arginine residues within proteins using co-substrate S-adenosyl-L-methionine (AdoMet, SAM), forming mono-methyl (MMA), symmetric-dimethyl arginine (sDMA) and S-adenosyl-L-homocysteine (AdoHcy, SAH). The enzyme activity was determined by following the product SAH formation using high throughput mass spectrometry (Agilent Rapidfire 300 System coupled to a Sciex 4000 series QTrap® triple-quad MS/MS). The reaction buffer was 20 mM Tris-HCl, pH 8.5, 50 mM NaCl, 5 mM MgCl₂ and 1 mM DTT. The reaction activity was stopped using 1% formic acid (final concentration).

Inhibition Studies.

The IC₅₀ Studies were performed using eleven point dosing series made for each compound by serially diluted 1:2 in dimethyl sulfoxide (DMSO), with point 12 being a DMSO control. Compounds were first spotted to plates, and followed by addition of 2 μM SAM and 0.6 μM H2A (histone H2A) solution mixture. The same volume of enzyme solution was added to initiate the enzymatic reactions. The final concentrations of the reaction are at 1 μM SAM, 0.3 μM H2A and 10 nM enzyme (assay 1a) or 1.25 nM enzyme (assay 1b). The reaction was incubated at 30° C. for 60 minutes (min) when 10 nM enzyme was used and for 120 min when 1.25 nM enzyme was used. Subsequently, the reaction was quenched by addition of formic acid to a final concentration of 1%. The inhibitions of SAH formation in the presence of compounds were calculated as a percentage of the control relative to the uninhibited reaction as a function of inhibitor concentration. The data were fit as follows: Y=Bottom+(Top−Bottom)/(1+10{circumflex over ( )}((log IC₅₀ −X)*h))

where IC₅₀ is the inhibitor concentration (same unit as X) at 50% inhibition and h is the Hill slope. Y is percent of inhibition, X is log of compound concentration. Bottom and Top are the plateaus in same units as Y.

Experimental Procedure PD Assay (Assay 2)

Reagents

A549 cells (ATCC, Cat #CCL-185) were cultured in Dulbecco's Modified Eagle's Medium (DMEM) (Sigma, Cat #D5796), supplemented with 10% Fetal Calf Serum (FCS) (HyClone™, Cat #SV30160.03), 100 mM Sodium Pyruvate (Sigma, Cat #S8636), 200 mM L-Glutamine (Sigma, Cat #G7513) and 50 mg/mL gentamycin (Gibco, Cat #15750-037).

Reagents used for buffers were purchased: Dulbecco's phosphate buffered saline (DPBS) without Ca/Mg (Sigma, Cat #D8537), phosphate buffered saline (PBS) 10× (Roche, Cat #11 666 789 001), Formalin solution 10% (Sigma, HT50-1-128-4L), Methanol 100% (Sigma, Cat #32213-2.5L), Triton X-100 (Acros, Cat #215680010), Bovine Serum Albumin (BSA) (Sigma, Cat #A2153), Alexa fluor 488 goat anti-rabbit antibody (Life Technologies, Cat #A11034), HCS CellMask Deep Red Stain (Life Technologies, Cat #H32721), Hoechst Stain (Life Technologies, Cat #33258), Anti-dimethyl-Arginine, sym (SYM10) antibody (Millipore, 07-412).

Immunohistochemistry Procedure

Cells were plated at 400 cells/40 μL/well in 384 well black μplates clear bottom (Perkin Elmer) and overnight incubated at 37° C., 5% CO₂. The IC₅₀ Studies were performed using nine point dosing series ranging from 10 μM to 1 μM for each compound. 80 nL of the respective dilution of the compounds was added using the Labcyte POD 810 (Labcyte) reaching a final DMSO concentration of 0.2% in cell culture. After an incubation period of 48 h at 37° C. and 5% CO₂, cells were fixed in 10% formalin solution for 15 min at room temperature and 20 min in ice-cold methanol, after which they were washed 3× in DPBS. Subsequently, the cells were blocked for 1 h in blocking buffer (PBS+1% BSA and 0.5% Triton X-100) and incubated overnight at 4° C. with the SYM10 antibody diluted 1/2000 in blocking buffer. The cells were washed 3× with washing buffer (PBS+0.1% Triton X-100) and incubated with the Alexa fluor 488 goat anti-rabbit antibody diluted 1/200 in blocking buffer for 1 h at room temperature. Subsequently, they were washed 3× with washing buffer and incubated for 30 min at room temperature with PBS containing a 1/5000 dilution of Hoechst Stain and a 1/5000 dilution of the HCS CellMask Deep Red Stain. After a final wash with PBS, the plates were imaged using the 10×W lens of the Opera® system (Perkin Elmer Life Sciences) using following settings (values in nm):

laser Filter camera Primary dichrome Detect dichrome 488 540/75 405/488/561/635 510 405 450/50 405/488/561/635 510 635 690/50 405/488/561/635 510

Analyses:

The inhibition of nuclear symmetric Arginine dimethylation in the presence of compounds (% effect) was calculated as the “median nuclear SYM10 intensity”/“median cytoplasmic SYM10 intensity”, normalized by below equation:

${normalized} = {100 - {\frac{{raw} - {lowMedian}}{{highMedian} - {lowMedian}}*100}}$

In the above equations, the following variable names are used:

normalized The normalized feature value raw The raw feature value lowMedian The median of the raw values of the low control wells highMedian The median of the raw values of the high control wells

In the above equations, the following controls were used for normalization:

Low control: minimum level of symmetrically dimethylated Arginines (cells treated with reference compound at 10 μM).

High control: maximum level of symmetrically dimethylated Arginines (DMSO treated cells).
